Abstract

The invention belongs to the technical field of curved surface photovoltaic devices, and relates to a technological process of a curved-surface photovoltaic device and a curved-surface photovoltaic device. The technological process comprises the following steps that: 1, a packaging material is laid on the surface of photovoltaic glass, a first packaging layer is formed, batteries are arranged on the packaging materials, the batteries are connected in series, so that a battery layer can be formed; 2, a second packaging material is laid on the battery layer to form a second packaging layer, and the surface of the second packaging layer is covered with backboard glass; 3, edge sealing is performed on the side edges of the first packaging layer, the battery layer and the second packaging layer by using edge sealing adhesive tapes to form a prefabricated sample; and 4, the prefabricated sample is pre-laminated, and a double-glass assembly is put into a laminating machine so as to laminated during pre-laminating. According to the technological process of the curved photovoltaic device and the curved photovoltaic device, the assembly can be bent, and the situation that the overall power is reduced due to breakage of the batteries is avoided.

Description

technical field [0001] The invention belongs to the technical field of curved photovoltaics, and in particular relates to a technological process of curved photovoltaics and curved photovoltaics. Background technique [0002] Building Integrated Photovoltaic (BIPV Building Integrated PV, PV stands for Photovoltaic) is a technology that integrates solar power (photovoltaic) products into buildings. Building integrated photovoltaics can be divided into two categories: one is the combination of photovoltaic arrays and buildings. The other is the integration of photovoltaic arrays and buildings. Such as photovoltaic tile roof, photovoltaic curtain wall and photovoltaic lighting roof. Among these two methods, the combination of photovoltaic arrays and buildings is a commonly used form, especially the combination with building roofs. [0003] As the carbon neutral plan continues to advance, the demand for building integrated photovoltaics (BIPV) is increasing. Now the mainstrea...
